Tie Rods

A tie rod assembly is generally used to brace heavy steel columns or timber beams or to support canopies and awnings. These are also used with clevises and/or turnbuckles. At BBI, we sport a unique Tie Rod Calculator which can quickly determine rod lengths provided overall pin-to-pin dimensions of a tie rod assembly are given.


Baseline Bolts manufactures tie rod or sag rod assemblies in a variety of ASTM specifications. Two common configurations are generally used. The first configuration is comprised of a single rod that is enveloped by a left hand thread & a right hand thread on either ends. A clevis is threaded onto both ends of the rod; when the rod is turned, the assembly is drawn tight. And, the second configuration is comprised of two rods that come with clevises on both ends and a turnbuckle in the middle. When the turnbuckle is rotated, the assembly can be drawn tight. At times, tie rod assemblies are connected using sleeve nuts or coupling nuts.

Most often, tie rods are manufactured using low carbon steel; but, we can also manufacture higher strength assemblies. Carbon or alloy steel tie rod assemblies are usually supplied with plain finish or hot tip galvanized. Well, stainless steel tie rod assemblies are also common.

Our expert panel at Baseline Bolts Inc can guide you in determining the appropriate rod length. To ensure perfect thread fit before shipping, we assemble the complete tie rod packages in our own facility.
